| Expected result | NDUFB10-positive staining in glandular cells of adrenal gland (HPA tissue IHC: High). HPA tissue profile: Cytoplasmic expression with a mitochondrial pattern in all tissues. No signal in the no-primary control. |
NDUFB10 is a mitochondrial inner-membrane protein with no annotated transmembrane segment (UniProt O96000 topology). In paraffin-section IHC, expect cytoplasmic staining with a mitochondrial pattern across tissues, including strong staining in specified glandular and neuronal cells (HPA: tissue IHC profile; High in glandular and neuronal cells). HPA rates the tissue pattern Supported, with medium consistency between antibody staining and RNA expression (HPA: reliability).
| Granular cytoplasmic staining in adrenal glandular cells or cerebellar Purkinje cells. | This fits the reported mitochondrial pattern and High staining in those cells (HPA: tissue IHC). Judge the pattern within identifiable cells; an entire section need not stain equally because HPA reports different levels among cell populations (HPA: tissue IHC). |
| Predominantly nuclear, surface-only or extracellular staining, without a mitochondrial-looking cytoplasmic pattern. | Treat the compartment as discordant: NDUFB10 localises to the mitochondrial inner membrane (UniProt O96000 topology), while HPA describes cytoplasmic expression with a mitochondrial pattern (HPA: tissue IHC profile). Check localisation and controls before interpreting it as NDUFB10. |
| Strong staining in adipocytes or chondrocytes while expected positive cells are weak. | These cells were Not detected in HPA tissue IHC (HPA: adipocytes; chondrocytes). Consider nonspecific antibody binding or endogenous chromogenic activity, then compare with a detection control. HPA's observation is a comparison point, not proof that every such cell must be negative. |
| Diffuse colour over cells and surrounding tissue obscures discrete cytoplasmic staining. | The slide cannot support a confident mitochondrial-pattern call (HPA: tissue IHC profile). In general IHC practice, background may come from nonspecific binding or detection chemistry; inspect a matched control before assigning the diffuse colour to NDUFB10. |
| No staining in a well-preserved section containing identifiable colon glandular cells. | Colon glandular cells are reported High (HPA: tissue IHC). A blank result calls for a technical check, but HPA's Supported rating includes only medium staining–RNA consistency (HPA: reliability); one negative section alone does not establish biological absence. |
| Compartment and topology | NDUFB10 is assigned to the mitochondrial inner membrane, with no annotated transmembrane segment (UniProt O96000 topology). For chromogenic IHC, evaluate the visible cytoplasmic pattern; the annotation alone cannot identify the exact epitope or establish a retrieval requirement. |
| Cell-specific tissue distribution | HPA reports High staining in glandular cells of adrenal gland, appendix, breast, cervix and colon, and in listed neuronal populations (HPA: tissue IHC). It reports Low in lung macrophages and bone-marrow hematopoietic cells, and Not detected in adipocytes and chondrocytes (HPA: tissue IHC). |
| Strength of pattern evidence | The tissue IHC profile is Supported, with medium consistency between staining and RNA expression (HPA: reliability). The listed antibody HPA073189 is IHC Supported; its ICC status is unreported in this payload (HPA: antibody validation). Interpret atypical results with that distinction in mind. |
| Transcript and processing annotations | Two isoforms are listed, while the recorded protein chain spans residues 1–172 without an annotated signal peptide or propeptide (UniProt O96000 isoforms; processing). These facts do not show whether an antibody recognises both isoforms or predict distinct staining patterns. |
| Fixation sensitivity | Target-specific fixation sensitivity is unreported in the supplied UniProt and HPA records. Choose and document retrieval conditions through the applicable IHC protocol and controls as general IHC practice; do not infer a NDUFB10-specific fixation effect from topology or tissue staining. |
| Situation | Likely cause | Next action |
|---|---|---|
| No signal in adrenal or colon glandular cells expected to stain strongly. | HPA reports High staining in these cells (HPA: tissue IHC), so a technical failure is plausible; the record does not identify its cause. | In general IHC practice, verify section quality, retrieval, primary-antibody use and chromogenic detection with an appropriate positive control before calling the specimen negative. |
| Strong colour in adipocytes or chondrocytes. | Those populations were Not detected in HPA tissue IHC (HPA: adipocytes; chondrocytes); nonspecific binding or endogenous detection activity is possible. | Compare a matched control and review the stained cells' identity and compartment. Treat persistent colour as unexplained until the control supports specific staining; HPA does not establish an absolute negative control. |
| Signal is mainly nuclear or outside cells. | This conflicts with mitochondrial inner-membrane localisation (UniProt O96000 topology) and HPA's cytoplasmic mitochondrial pattern (HPA: tissue IHC profile). | Check counterstain interpretation, tissue morphology and control staining; score only convincing cytoplasmic signal in identifiable cells as consistent with NDUFB10. |
| Diffuse brown background hides the cellular pattern. | Background from nonspecific binding or chromogenic detection is possible under general IHC practice; the supplied sources do not assign a NDUFB10-specific cause. | Use a matched detection control, then review blocking, washes and detection conditions as general IHC troubleshooting. Reassess only where cellular localisation remains visible. |
| Macrophages look weaker than nearby strongly staining cells. | HPA reports Low staining in lung macrophages, while several listed glandular and neuronal populations are High (HPA: tissue IHC). | Compare each cell population with its own HPA reference level and morphology. Do not require macrophages to match a High-staining positive control. |
| Can the IHC pattern be used as an IF/ICC validation claim? | HPA supplies no ICC-IF image or main-location assignment here, and ICC validation for HPA073189 is unreported (HPA: subcellular record; antibody validation). | Use the separate IF/ICC guide for that application. Treat mitochondrial inner-membrane localisation as a biological expectation (UniProt O96000 topology), not as demonstrated ICC staining. |

Use the catalog antibody’s paraffin-section method as the IHC starting point, then judge staining against NDUFB10’s expected mitochondrial pattern (datasheet A11886-3; UniProt O96000).
A11886-3 has IHC images from paraffin sections of human, mouse and rat tissue, plus an IF image from MCF-7 cells (catalog image captions).
A11886-3 has IHC images from mouse and rat skeletal muscle and human prostate and gastric cancer paraffin sections (catalog IHC captions). The same SKU has an IF image from MCF-7 cells (catalog IF caption).
Which to pick: For tissue IHC, choose A11886-3, a rabbit antibody with paraffin-section images across the listed tissues (catalog host; catalog IHC captions). For IF/ICC, the same SKU lists both applications and has an MCF-7 IF image (catalog applications; catalog IF caption). For cross-species work, A11886-3 lists human, mouse and rat reactivity; its paraffin-section captions do not report the fixative (catalog reactivity; catalog IHC captions).
